Radial carcass tire for a civil engineering vehicle, having two bead wires (2) of radial height Ht, and carcass reinforcement made of two layers, the first (1) being radially innermost with a radial height Hdc, is anchored in each bead to form a main part (11) and a turn-up (12). The second layer (3) is radially outside the first layer (1). The free end (A) of the turn-up (12) is at a radial distance from the radially outermost point (21) of the bead wire that is at least equal to 1 and at most equal to 2 times Ht. From the end A of the turn-up (12) to the point B at 85% of the radial height Hdc, the distance between carcass layers is at least equal to 2 and at most equal to 11 times the diameter of metal reinforcers of first carcass layer (1).
